Navajo Page 22 Condor-Cont. california Condor Eben McMillan Feb. 22-1963 when the Condor, formally mentioned, flew from the Ground the first time we noted a feather missing in the right wing about the 6th or 7th primary in from the end of the right wing When it flew the second time it circled a few times above the feeding area. On one of the turns, a Primary feather fell from the right wing that turned out to be one on either the outer, or inner, side the gap that was caused by the previously missing feather. This feather is Specimen No.1 in my Condor material. Its overall length is 25 1/4 inches The distance from the root-end to the first barbs and the depth which the quill was imbedded was 3 1/2 inches. The width of the feather at its widest point was 3 1/8 inches The height of the bend at its maximum from the horizontal was 3 1/2 inches. at 11:00 A.M. When we first saw this bird the sky was overcast with low foggy clouds coming across on a brisk, and cold, east wind. At NO time during these observations did we see enough color on its head to identify it as an adult bird. Sang Condor -> notatured food Driving to the lower end of the Navajo creek we came upon a Condor that showed much Orange on the head, as it fed with several Turkey Vultures on the carcass of a dead Ewe Sheep. The sun was not shining brightly, it being 12:10 p.m., and the cold east wind was not blowing here. As the bird left, as it did after we watched it for about Three minutes, it flew directly above us at a height of about 150 feet. We could easily make out the gap of at least 2 missing outer Primary feathers in the right wing, about 6 and 7 or 7 and 8 from the end, Continue to Page 3
